Try removing the data cable and power cables.  (turn it off first)
To the hash boards you dont want running.

Switch the firmware to braiins OS and do the suggested above again.

The suggested above should be work because bitmain has a guide that you need to test the hashboard one by one so it means it should run even one hashboard. You might be have a faulty hashboard that is why you are getting error when running one hashboard. Try to use Braiins OS or check your Ethernet connection.

S9's should run fine on any number of boards, suggest testing each one in turn to find the dead one.

True: I'm running my reference one with two boards enabled so I can run it on a 120 volt power line. Two boards using stock firmware results in about 9th speed at slushpool with 1,000 watts being pulled at the power plug. Which oddly enough seems to be about the same as running three boards in "low power mode". Go figure.

The S9 miners do not need all three boards, a single board works. You have another problem. Of course two boards also work.

I have 27 s9 units.

three boards. 23
two boards.    3

they work. so your issue is something else.
